Baylor University researchers working with McGill found that if you suppressed PKR, a molecule in the brain that normally regulates how neurons talk to each other, gamma interferon steps in and cranks the neural communication up, improving memory and overall function.

When tested in mice, they showed increased memory and neural functioning with no ill effects. It’s believed that this might be the wonder drug for Alzheimer’s, or at least substantially improve the quality of life for Alzheimer’s patients. But, as the researchers point out, there’s no reason healthy people couldn’t take it. They just wouldn’t be allowed on Jeopardy.
